Hello all. There is a hot, 12V terminal at the bottom of the fuse box that is no longer getting power. Is there a fuse to this and if so, where? Or, where can I find a wiring diagram.

Thanks!

OK, let's see if this works. The terminal is right in the middle of the photo with a Phillips screw holding down the wires.

What is the terminal number on the top, the screw will match one tab ?

Is there anything not functioning ?

that does not appear to be MB wiring... I'm guessing here, but it looks like a stereo guy or alarm guy installed that stuff.

the sticky thread at the top of this forum, should point you to the fsm, and the electrical section should help you determine what feeds this circuit.

Thanks for guidance to the wiring diagram. With that in hand I found a blown fuse in the over voltage protection relay.
